FRANCIS H. CAMPBELL, 0F FLUSHING, NEW YORK, ASSIGNOR T0 IV'IERGENTHALER LINOTYPE COMPANY, A CORPORATION OF NEW YORK.

TYIPOGRAPHICAL MACHINE.

T 0 all whom it may concern Be it known that I, Framers H. CAMPBELL, a citizen of the United States, residing at Flushing, in the county of Queens and State of'New' York, have invented certain new and useful Improvements in Typographical Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention has reference to typographical casting machines, such for instance as linotype machines, wherein a slug or bar is cast in a slotted mold against a composed line of matrices, which is presented temporarily in front thereof and serves to form the type characters on the edge of the slug. The mold employed in such machines usually comprises cap and body portions, constituting the upper and lower walls of the mold slot, and two intermediate elements or liners, constituting the end walls thereof. It is frequently necessary to change the size of the mold in order to produce slugs of different lengths; and this result'is usually secured by removing one of the liners and substituting another of a width corresponding to the new length required. The liner commonly employed is somewhat similar to that shown in U. S. LettersPatent to G. A. Bates, No. 618,55 i, and is of such construction that it may be withdrawn forwardly from the mold without requiring the removal of any other of the parts.

Inpractice some difficulty is experienced in effecting the removal of the liner, due to its tendency to adhere to the cap and body and to their pressure thereon. In some instances, the operators or machinists resort to the use of a screw driver or other hard tool, which method often results in serious injury to the liner or the mold parts. It also happens that sometimes the liner is so badly mutilated as to cause burs or fins to be formed thereon, and so as to prevent the mold cap from seating firmly in place.

It is the object of my present invention to avoid the necessity for these objectionable methods, and to that end I provide suitable means whereby the liner may be easily and instantly removed when required. In the present instance, such means comprise a movable ejector arranged on a fixed rear support and adapted to engage the liner and push it forwardly out of the mold.

Specification of Letters Patent.

Patented Dec. 21, 1915.

Application filed January 30, 1915. Serial No. 5,165.

In the accompanying drawing, I have shown my invention as applied merely by way of example and in preferred form, and obviously many changes and variations may be made therein without departing from its spirit. I therefore desire it to be understood that I do not limit myself to any specific form or embodiment, except in so far as such limitations are specified in the claims.

Referring to the drawing: Figure 1 is a perspective View, partly broken away, of a portion of a linotype machine having my invention applied thereto; and Fig. 2 is a sectional detail thereof.

One or more molds A are mounted in the mold wheel B, which is jo-urnaled upon the arm C extending laterally from thezmold slide (not shown), all in the customary manner. The mold comprises as usual the body portion A the cap portion A and the intermediate liners A and At, providing between them a longitudinal slot open at the front and rear wherein the slug is cast, the

slot during the casting action being closed at its front by an assembled line of matrices presented momentarily to the mold, and closed at its rear by the mouth of the casting pot from which the molten metal is forced I of different size.

As before stated, the resistance offered by the liner often causes considerable trouble in effecting its removal by hand, and I therefore provide mechanical means whereby this operation may be effected speedily and without difficulty. In the form shown, these means comprise an ejector E slidably sup ported on the arm C and formed with elongated slots E which embrace studs C secured to said arm, the studs serving to guide the ejector and also to limit its movement in opposite directions. At its forward end, the ejector is formed with a reduced portion E which is adapted to engage the rib A and travel in the transverse groove in the body portion A during the ejection of the liner and thus avoid injurious contact with the other parts. The ejector is held northe moldwithits liner A in position to be moval of said element, and a carrier for the,

engaged by the ejector E, this position of the parts being shown in Fig. 1. The ejector is then moved forwardly by the lever F andpushes the liner before it out of the mold, the reduced portion E passing freely between the cap and body portions, as shown by full lines in Fig. l and by dotted lines in Fig. 2. When the liner .is thus removed, the lever F is released by the operator and the spring D returns the parts/to" their original position. i

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States, is as follows:

1. In a typographical casting machine, the combination of a longitudinally slotted moldopen at the front and rear and including a removable element which determines the size of the mold slot, and means mounted in the machine and operable to effect the removal of said mold element when required.

2. In a typographical casting machine, the combination of a longitudinally slotted ment, a movable ejector mounted upon a fixed support and adapted to effect the remold to present it in cooperative relation to the other casting devices and movable tolo- Uopies of this patent may be obtained for five cents each, by addressing the Washington, D. 6. f

cate it with its removable element in tion to-be engaged by the ejector. V

4. In autypographical casting machine, the combination with a longitudinally slotted mold, comprising the cap portion A the body portion A and the intermediate liner A constituting one of the end walls of posithe mold slot and formed with the trans,

verse rib A to engage in a corresponding groove in the body portion, of the movable ejector E arranged upon a fixed support and adapted to engage the liner and pushitfor wardly from the mold,

5. In a typographical machine, the combination of a mold including a removable element, a movable carrier to present the mold cap and body portions and an intermediate removable liner, of an ejector movable between the cap and body portions to effect the removal of said linen-the said ejector being reduced at its active endso as to facilitate its passage between the cap and body portions of .the mold in its ejecting action.

7 In a typographical machine, the combination of a mold including a removable element, a movable carrier to present the mold in cooperative relation to the other casting devices, a movable ejector, a spring to hold the ejector in its normal or inactive position out of the path of the movement of the mold carrier, and a device for moving the'ejector against the action of the spring to efiect the j removal of the mold element. a I In testimony whereof, I have afiixed my signature in presence of two witnesses: FRANCIS H. CAMPBELL.
